Controlling the lower player sucks.
Upper player gets 90% of the map, plus fortress, plus 5000 resource income every 15 seconds. Plus he gets prebuilt fully-upgraded barracks and Stables. If I control the top, lower player loses in less than 2 minutes even before building the first barracks.
Well, it has walls.
Map Design: 1.5
I counted 2 textures throughout the whole map.
Not sure what you mean by slightly unbalanced.
